To all whom it may concern:

Be it known that I, JOSEPH KLEIDMANN, 1: sobject of the Czar of Russia,and resident oi the city of New York, in the county of New York andState of New York, have inand useful Improvements in Feeding-MachineAttachments for Printing-Presses, of which the following is a specification.

The present invention relates to improvements in feeding machineattachments for printing presses, and is adapted to be attached to anywell known form of feeding machine for printing presses, ruling machinesand the like. More particularly, the invention relates to means forregistering the sheets of paper as the same are fed on thefeedingfisable to the press cylinder of the printing presses.

The registering devices, heretofore in use, may be divided into twogeneral classes, that is, first, such devices which push the sheet ofpaper into its proper position, and, second, devices which'pul the sheetinto its iroper place. The first class is objectionable imthe reasonthat the sheet is very often, due to the adhesion of the paper to thefeeding board waved or buckled, and, when consequently released from there istering apparatus, springs sidewisc, whereby it is brou ht out ofits registering position. These eviccs, heretofore in use, which pullthesheet into its registering Iposition, are defective for the reasonthat w ien the re istering apparatus is about to release the s ieet ofpaper to be fed. into the printing press, the movable part of theregistering apparatus very often pulls the sheet out of its registeringposition.

It is now the object of the resent invention to obviate the aforesaidefects; and to that'end the invention consists in the combination, witha. printing press and mechanisms automatically supydying the aper tosaid press, of a registering device, t 1e sheet gri ping part-of whichis slidably and resiliently supported by ti 1c swinging portion of theapparat'us, and is caused by suitable means to inove in a substantiallyvertical line when disengaging the sheet, wliorel'iythe same is pt inits registc'rin osition.

Other ob'octs wil 1e apparent from a reading of t e specification and anexamination of the drawings, forming part of the present application.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a side elevation of a paper feeding a paratus, having theattachment, forming tie subject matter of the present ap 11ication,attached thereto, 2 a top-plan F1 view of about one-half of theattachment,

Fig. 3 is a side elevation of the re istering device, showing theposition of the sheet grippin part, when about to engage the sheet 0paper, Fig. 4 is a similar view of the apparatus, showing theregistering device in a position, whereby the sheet of paper is engagedand drawn into the registeringpositiou, and Fig. 5 is asiinilar view,the sieet gripping part moving upward, whereby the sheet is disengaged.Fig. 6 is a top View of the registering device, while Fig. 7 is aperspective view of a detail of construction.

It it ill be observed that in Figs. 1 and 2 of the drawings, only thoseparts of the feeding machine are shown, which are necessary tounderstand the operation of the registering apparatus, and as shown inFig. 2 of tho. drawings, about one-half of the operating mechanism ofthe registering device is illustratcd, it being understood that the samearts and devices are applied on the other iiall of the :ittaclnncnt.

In the drawings, 1 designates one of a pair of the side frames of thefeeding machine, connected to the side frame 2 of the printing press. -The stack of paper is indicated in the drawin s at 3 and is supported bya table 4, prefera )ly automatically raised as the sheets are fed fromthe same.

T he sheets are brought by the feedin mechanism unto a forwardly bcntlip 6 am thus u .101! the feed table 7, wherefroni they are fe unto thepress cylinder 8, suitably geared with the main shaft 9 of the feedingapparatus, which main shaft governs the motion of the feeding mechanism5 and of the registering apparatus, hereinafter to be described.

- Attention is called to the manna a registering device for the paper isarranged on each side of'the machine and'obvioiislv one i of thosedevices is used when one side (if the paper is being printed, while theother is made use of when printing the reverse side of g the sheets. Indescribing theselegistering devices, it isthought that only' one of thesame is to be considered, the other being which rests on the feedingtable 7, and the respectively.

t er

leg 12, arranged at right angles to the leg 11, serves as a guide forthe sheets. Dbviously the leg 12 is arranged at right angles to the mainshaft 9 of the ap aratus and thus parallel to the side edges oi thesheets, moving onthe feed table 7. The frame 10 is secured to asubstantially square block 13 by means of screws 14, which square blockis ada ted to reciprocate inguiding slots 15 of the eed table 7, whichguiding slots run parallel with the axis of the press cylinder 8. Theframe 10 supports the re istering apparatus, here inafter to be described.

The registering apparatus, as will be seen, moves to and fro the centerof the feed table, and for that purpose the square block 13 isadjustably mounted upon a rod 16, arranged parallel to the axis of thepress cylinder, and engaged by a bellcrank 17, fulcrumed at 18 to theupper side of the table; the free end of the bellcrank is engaged by aconnecting rod 19, which in turn is pivotally'connected to the arm 20 ofa two-armed lever 21, ivoted to the frame of the machine at 22. he freeend of the arm 23 of this lever carries a roller 24, engaging a cam 25,arranged on the main shaft 9 of the feeding a paratu's, and controllingthe movement 0 the registering device. To impart the reciproc tingmotion of the rod 16 to the r ten (i evic'e arranged on the other side 0the ta lo, a two-armed lever'26 is mounted on the feed table 7 andconnected by means of connecting rods 27 and 28 with the alternatingrods 16 and 16,

The registering device comprises fur more the register arm 29 pivoted toa bracket 30, arranged on the vertical leg 12 of thesupport or frame1.0.1 The free end of this arm 29 carries slidabl'. arranged thereon ablock 31, adapted 'to slide in the plane of the arm 29 in a direction atright angles to the s indle 32 updn which the arm 29 oscillates. or thispurpose the 'block 31 is bifurcated at 33 and engages the arm 29, whichis provided at its lower portion with a slot 34 e aged by a-pin 35,arranged on the bifurca-t'e portion of the block 31. To more safel guidethe block 31 the latter is provide with a hole 36 in its upper extension37, and engaged by a s indle- 38,, secured to the arm 29 and providewith a head 39, between which and the extension 37 j of the block 81 isarranged a helical spring 40, normally keeping the block 31 in its innerposition upon the arm 29. A roller 41, having preferably a rnughcovering, such as rubber, is arranged on t e block 31 on a spindle 42,

whereby the roller ma revolve in the direction of the travel of t esheets. This roller 41 may be kept in contact with the sheet 43, restingon the leg 11 of the frame, by means of a spring 44, en aging the arm.29 at 45 and wound around t e spindle 32, upon which the arm 29oscillates. The arm 29 is furthermore provided near to its front endwith a hole 46, in which is arranged a pin 47, .carried b a spring 48,arranged on the arm 29, whereliy the pin is forcedto protrude throughsaid opening, but at the same time is adapted to be ressed inwardly bythe block 49, arranged on the table 7 of the ap aratus; This block 49 isadjustably arrange 'in the slot 15 of the table and is provided with a'sto 50 in the path of the block Sfl, carried by t e arm "29 of the aparatus. The pin 47 protrudes through the ole 46 of the lever 29, and,obvionsly, in the backward movement the ap- Earatus would be preventedin its movement y the block 4'9, arranged in the path of the pin, wereit not for the tapering oove 51 in this block, in which the pin s desand is pressed against the tension of the sprin out-' wardly, so that itcomes to contact wit the inner side of the block.

The operation of the registerin device is as follows: First the block 13and thus the 'moving part of the re ister is'arranged in its properosition upon t 6 rod 16, corresponde' width of the sheets to be fed;then the block 49 is moved in the slot and secured against movement at aplace where it is intended to disengage the sheet of paper, that iswhere the sheet is 111 its register ng position. When the registeringdevice is in its outermost position the pin47 rests upon the inclinedupper surface'52 of the bloc 49, as will be hereinafter described;thereby the roller 41 is kept at 'a certain distance from the leg 1 l ofthe frame 10. I As the registering device new moves toward the center ofthe table-to engage a sheet, thesheet will be brought,to ay-. a ainsttheviertical leg 12 of the frame 10 an thusbe in a position to begripped. The registering device having moved forward, the roller iscaused to engage the sheet of page! by the spring 44, as soon as thepin. is 'sen aged withthe inclined surface 52, or in o't or words whenthe pin arrivesat the front ed e of the block 49. It is obvious that there e1'41hand the leg -11 of the frame 10 form coacting grip ing jaws,engaging the sheet. Thecam 25 t en causes the registering ap aratus tomove outward fremt epenter o the table and pull thus the sheet in apredetermined registering position. The tapering groove 51'allows theregisteringlapparatus to move backward, by pressing t efpin 47 inward!so that itemtacts with the inner side 0 the wall of the block 49. Assoon as the forked end 33 of block 31 comes in contact with the stop50.,

or in other'words, into the position in which the sheet should be releasd, the roller 41 .moves upward by sliding upon the curved surface of thestop 50, whereby the sheet is disengaged and allowed to pass unto thepress cylinder of the printing press.

It will be seen that, since t e block 31 is slidably arranged on the arm29,- and although the arm 29 moves further outward, the block 31 will beallowed to stop for a time and then move for a predetermined time in avertical line upwards, or in other words, will move with a speed equalto zero in the direction of travel of the registering device for apredetermined time, by reason of the stop 50, whereby the sheet of paperis properly disengaged in its registering position. The arm 29 swingsfurther upward, whereby the pin 47 engages the taperingsurface 52. Thecam 25 forces the reci n'ocating rod 16 then again toward the center ofthe table to carry the registeringdevice forward in the position toengage the next sheet of paper.

It is obvious that the apparatus can be rdapted to operate on paper ofdifferent widths by adjusting the movable element and the stationaryelement of the same on the reciprocating rod 16 and in the slot 15,respectively. It is obvious furthermore that various minor changes maybe made in the construction of the device and al'scin the arrangement ofseveral parts without departing from the spirit and scope of the presentinvention.
